Refactored driver.Std* traits for inclusion of StdListTables
Introduced StdListTables trait
Changed schema initialization to fail properly on errors

Previously schema creation would take any exception to mean a table already
exists. Changed so a manual check for existance is performed beforehand, and
other exceptions are not swalloed.
Scala 2.10.2
Fix tests
Merge branch 'danielkza-0.3' into 0.3
